"I'm amazed by how many people I meet who can't wrap their head around what I do," Rosalee tellsthe San Francisco Gate. "I get judged a lot. They think monster truck driving is brainless...that we just want to go out and smash things up. But there's a lot of planning and thinking that goes into it."

She started competing professionally about two years ago, and has so far entered 24 shows.

“Being in a truck with 1,600 horsepower is unlike anything else that you’ll ever experience,” she tellsABC. “And getting to step on the throttle is really amazing.”

At the age of three, Rosalee started learning how to build engines from her father, who spent hundreds of hours under the hood of a car.

"It's kind of fun now to watch her come home from computer programming classes and explain what happens and why it happens," Kelvin says. "And I'll show her how I did it and survived without an engineering degree."

Rosalee is now attempting to design the first electronic fuel injection system for a monster truck.

Incidentally, she may also be the youngest American certified to clear a semi-truck from a freeway during rush hour -- something she learned to help out her father's business.

In the mean time, Rosalee doesn't seem to be bothered too much by the rumours about her age and gender at monster truck competitions.

"You can tell when they don't want 'the little girl' to beat them out, so they try going for something they wouldn't normally do," she explains. "And then they crash or break a wheel off."
